Update

Ok i manged to figure out how to connect and rig the tie to the hitman with out creating any deformation or other problems. However Dan i follwed the steps you e-mailed me on using deformation for the top of the tie and the belt buckle. The steps i used were:

Smooth bind the tie joint to the tie,
parent the tie joint to the hipsmanip
parent the tie to the mesh
the bind the rig to the mesh

At the moment i am currently weighting up the hitman elbow, managed to do his arm at a good standard and everything else is comming on smoothly. Heres a pic of the tie inactionm, i still need to make control though
